LLVM ERROR: Cannot yet select: 0x2625340: f64 = ConstantFP<3.540000e+02> :What is it?

Hi Christoph
I am compiling for x86-64. This error happens randomly (at least it
appears that way) and rarely. About every few thousand runs

Hi Gabi,

the only useful advice I can give you right now: Try to narrow the
problem down. You'll have to find out where the "problematic" constant
3.540000e+02 comes from and boil it down into a test case.

Regards,
Christoph

Does this reproduce with llc? If so, you can use bugpoint to reduce it to a small testcase.
